Ok.. So as previously stated...

Im new to the turbo world.

But i am curious on what list of bolt ons can i buy that will not require a tune? As of right now my in near future mod list is.

Plugs
Velossa Big mouth
Drop in
Symposer delete

My questionable mods are
3" exhaust
Hot/cold pipes
Silicone replacement on intake?

Any of those are okay without a tune, no need to change plugs until you start making significantly more power.

i am asking about plugs because i have 74K miles on my car.

At 74k I'd suggest new plugs

Change plugs and stick with motorcraft
